ABSTRACT Background: chronic periodontitis and rheumatoid arthritis are widely prevalent diseases and are characterized by tissue destruction due to chronic inflammation. Recently, there is growing evidence that the two diseases share many pathological features the aims of the study To determine the periodontal health status in patient have chronic periodontitis with rheumatoid arthritis and compare it with those having chronic periodontitis without Rheumatoid arthritis and determine the serum levels of interleukin -17(IL-17), tumor necrosis factor- alpha (TNF-α ) in both groups and compare with the control group (subject samples neither have periodontitis nor arthritis ) and correlate these immunological markers with the periodontal parameters Plaque index , gingival index , bleeding on probing, probing depth, clinical attachment level and number of missing teeth. Materials and methods: Eighty (80) males and females subjects with age range (30-45) years were recruited in this study they were divided into three main groups The chronic periodontitis with rheumatoid arthritis group consist of thirty (30) subjects and second group consist of thirty (30) subjects have chronic periodontitis and third group consist of twenty (20) subject case control group. All subjects had normal weight and height range according to BMI (body mass index) that it value is (18.5-25), Clinical periodontal parameters used in this study were Plaque index, gingival index, bleeding on probing, clinical attachment level index, probing pocket depth and number of missing teeth was measured in all groups at four surfaces of all presented teeth Blood samples were collected from all individuals and examined to determined serum level of interleukin -17 and tumor necrosis factor-a by mean of enzyme-linked immune–sorbent assay. Results: The present study showed patients with chronic periodontitis and rheumatoid arthritis had higher prevalence of sites presenting dental plaque, a higher rate of gingival inflammation and bleeding on probing greater probing depth, greater attachment loss and high number of missing teeth compared to those had chronic periodontitis only and control subjects . Also highly significant differences between studied group regarding serum level of IL-17 and TNF-α atp < 0.001, as well as, it revealed that mean serum levels of IL-17 were statistically higher in chronic periodontitis with rheumatoid arthritis group (607.9 ± 79.9) than Chronic Periodontitis group (421.4 ± 5.9) and Control groups (15.9 ± 2.7) similarly serum level of TNF-α (402.2 ± 41.2 319.4 ± 526 85.3 ± 4.9) respectively at p < 0.001. Regarding correlation, the current study observed strong positive correlation between serum levels of IL-17 andTNF-α with PL.I, GI, BOP, PPD CAL and the number of missing teeth in the PRA at p<0.001. Also this study reveal significant correlation between the two immunological markers (TNF-α and IL-17) in chronic periodontitis with rheumatoid arthritis group and in Chronic Periodontitis group. Conclusion: It was concluded that there was higher potentiality to chronic periodontitis involvement among rheumatoid arthritis patients, that correlated positively with increase the level of serum levels of IL-17 and TNF-α accordingly with high score of clinical parameters that had recorded. That mean TNF –a and IL-17 may play an important role in increase the severity of periodontitis as well as rheumatoid arthritis
The research studied and analyzed the hybrid parallel-series systems of asymmetrical components by applying different experiments of simulations used to estimate the reliability function of those systems through the use of the maximum likelihood method as well as the Bayes standard method via both symmetrical and asymmetrical loss functions following Rayleigh distribution and Informative Prior distribution. The simulation experiments included different sizes of samples and default parameters which were then compared with one another depending on Square Error averages. Following that was the application of Bayes standard method by the Entropy Loss function that proved successful throughout the experimental side in finding the reliability fun

Treatment of greywater can range from uncomplicated coarse filtration to advanced biological treatment. This article presents a simple design of a small scale greywater treatment plant, which is a series of physical and natural processes including screening, aeration, sedimentation, and filtration using granular activated carbon filter and differentiates its performance with sand filter. The performance of these units with the dual filter media of (activated carbon with sand) in treatment of greywater from Iraqi house in Baghdad city during 2019 and that collected from several points including washbasins, kitchen si

The purpose of our study was to develop Dabigatran Etexilate loaded nanostructured lipid carriers (DE-NLCs) using Glyceryl monostearate and Oleic acid as lipid matrix, and to estimate the potential of the developed delivery system to improve oral absorption of low bioavailability drug, different Oleic acid ratios effect on particle size, zeta potential, entrapment efficiency and loading capacity were studied, the optimized DE-NLCs shows a particle size within the nanorange, the zeta potential (ZP) was 33.81±0.73mV with drug entrapment efficiency (EE%) of 92.42±2.31% and a loading capacity (DL%) of 7.69±0.17%. about 92% of drug was released in 24hr in a controlled manner, the ex-vivo intestinal p
